I found the session really helpful, it definitely helped to target my main problems then work at them individually before putting them together. I would definitely have another tutorial!

Jess, Student

Kane is a true professional. He was thoroughly prepared and delivered a wonderful, confidence-boosting tutorial. Besides his expert knowledge and the ability to address problem areas as well as teaching the subject, my son found Kane incredibly kind and easy to talk to.

How is MyTutor different from school?

Lots of students say that the classes are too big in school, or that they don't have time to ask teachers after Online Lessons. In my Online Lessons, we take time to explore things in a little in a bit more detail.

How does myelination of neurones increase conduction velocity?

Myelination is the production of a myelin sheath - a fatty, electrically insulating layer formed by Schwann cells wrapping around the axons of neurons. This sheath is not continuous, there are gaps between Schwann cells which are called nodes of Ranvier. At these nodes, the axon membrane (containing sodium and potassium ion channels) is uncovered/exposed to ions in extracellular solution. Therefore depolarisation can only occur at the nodes of Ranvier. Since the action potential jumps from node to node (this is called saltatory conduction), the action potential travels a greater distance for a shorter period of time. In an unmyelinated axon, every single section of the membrane will have to be depolarised for the impulse to conduct along the axon, hence taking more time.

What is the doctrine of precedent? / What are its advantages and disadvantages?

A doctrine or policy by which the lower courts in hierarchy are required to follow rules or principles laid down in previous judicial decisions by higher Courts. (Latin: 'stare decisis' - to stand by decided matters)
In order for previous decisions to be binding on new ones and thus form the doctrine of precedent the previous case:
1. Must have been decided by court of sufficient status in court hierarchy,
2. It must still stand as ‘good law’ (i.e. not overruled)
3. There must be sufficient degree of analogy between the precedent case and the case being decided.
All 3 conditions must be met, otherwise the previous case will not be regarded as binding, but rather as persuasive.
Note: the previous decision does not always have to be applied. It can be distinguished, or even overruled (if the court is at a sufficient hierarchy to be permitted to overrule - i.e. Supreme court).
ADVANTAGES:
-predictability
-certainty
-avoid ad hoc decision making
DISADVANTAGES:
-inflexibe
-stagnation
GENERAL DEBATE: certainty vs justice.

How should I structure an opinion essay in Spanish?

The easiest way to approach an essay is to follow the standard formula: “introduction + development + conclusion”. The number of paragraphs you should aim for will depend on the specific task. For example, for the typical question asked in the A levels (250 to 400 words) I would recommend to use four or five of them. Let’s see an example:
-----
“El mundo del transporte va a cambiar mucho debido a las innovaciones tecnológicas. ¿Qué
opinas tú?”
En el primer párrafo de introducción, compararía brevemente los sistemas de transporte actuales frente a los de finales del siglo XIX, y mencionaría como, en el pasado, dicha evolución ha ido ligada al desarrollo industrial. En el segundo párrafo hablaría de las necesidades del sistema actual, y expondría por qué creo/no creo que un avance tecnológico puede mejorarlo. En el tercer párrafo trataría ejemplos concretos a favor de mi tesis. Finalmente, en el cuarto párrafo añadiría un último ejemplo (o un resumen de los anteriores) y concluiría resaltando de nuevo la tesis.
However, you should bear in mind that there is not a single way to answer an essay question. It is also very common to use a deductive structure, in which we start by stating the thesis (as a universal truth). Then we support this with a series of examples.

Find the set of values of k for which x^2 + 2x+11 = k(2x-1)

The discriminant for a quadratic polynomial of the form f(x) = ax^2 + bx + c is given by b^2 - 4ac. If the discriminant is strictly greater than 2, the quadratic has 2 real distinct roots, i.e 2 unique x-values for which f(x) = 0. This fact can be used to solve the question. First of all, rearrange the above quadratic and equate to 0. Next use the equation of the discriminant to get a polynomial in k. Find the critical values of k and hence calculate the constraints on k.
(1) X^2 + (2-2K)X + (11+K) = 0; (2) 4k^2 - 12k - 40 > 0, k^2 - 4k - 10 > 0; (3) k < -2, k > 5

Explain how proteins can be used as a respiratory substrate.

When supplies of carbohydrate and lipid are inadequate, the body can use protein as a respiratory substrate- in times of prolonged starvation, tissue protein from muscles can even be broekn down for this purpose. The proteins are hydrolysed into their constituent amino acids, which are then deaminated in the liver. The amino groups are converted into urea and excreted in the urine, and the remaining amino acid residues are converted into acetyl CoA or pyruvate by enzymes- both of which are intermediates of the Krebs Cycle. The Krebs cycle then continues the process of respiration.
